摘要：

The permeability and resonance frequency of Permalloy microparticles dispersed in an insulating host depend on the particle size. The Maxwell-Garnett theory is not accurate to interpret the experimental results. The Bruggeman theory is modified in order to take into account the effect of eddy currents and gives a very good agreement with experiments.
